Confirmed - the [[POP3]] server answers connections, authenticates users, and can access its mail store - in this case, we can see that there is a message queued up and waiting for delivery. (Note that frequently you may NOT see any messages in the queue on a POP3 server, as most organizations using POP3 expect users to download their mail and delete it as soon as they have.)
